Absence of Non-Trivial Fuzzy Inner Product Spaces and the Cauchy–Schwartz Inequality

First, we show that the non-trivial fuzzy inner product space under the linearity condition does not exist, which means a fuzzy inner product space with linearity produces only a crisp real number for each pair of vectors. If the positive-definiteness is added to the condition, then the Cauchy–Schwa...
